  • Display apparatus including self-tuning circuits for controlling light modulators
    Patent number: 9818347
    Abstract: This disclosure provides systems, methods and apparatus for controlling the states of a light modulator used in displays. A display apparatus includes pixel circuits coupled to the light modulators. Each pixel circuit can include an output node, a data capacitor, a charge transistor for charging the output node and a discharge transistor for selectively conducting a current between the output node and an update interconnect providing an update voltage. The display apparatus can include a controller for testing the pixel circuits to determine two or more update voltage levels, each update voltage level causing the discharge transistor to conduct current. The controller also can be configured to determine a logical high voltage level to be stored in the data capacitor based on the plurality of update voltage levels.
